"Gone are the slowly stumbling zombies of earlier generations, replaced by a frantic horde who dive, tackle and bite like a snarling biblical horde of rats, a mass of bodies that wail and gnash teeth, thrashing insatiably in search of human flesh. And although plenty are slaughtered by Pitt and company, the gory details are spared, Foster wisely playing this as thriller rather than splatter. With all the action, there's little time for character development or heart, but Pitt holds his own as an hero with a mission to save the world. And given what he goes through, it's just as well he's more indestructible than the average zombie." - Simon Weaving, Screenwize
